I recently started taking 10 Units Novolin Insulin at bed time. This has improved my morning blood glucose readings significantly, as well my b4 dinner BG readings are good too. I also take 2 Metformin 500 with breakfast and a third with lunch. My concern is my b4 lunch BG #'s are always high, 160 - 177. The only conclusion I can make is that the Insulin takes an afternoon Siesta, LOL. : ) Please share your thoughts and experiences.

are you eating anything in between breakfast and lunch that might spike you BG level?

one of the 1st days, I ate a totally healthy breakfast and morning snack and it still spiked to 170. There may be some eating issues, not necessarily at that time.

The other thing..I recently started taking a nightly shot of insulin too..It's been a little over 3 months ago..It took awhile before my numbers started to level out..I test atleast 3 times a day and at first I would get a spike at different times of the day.
Now they stay pretty close..and alot of that is due to diet and exercise..Wish you luck I know this can be fustrating

what kind of Novolin? NPH? R? 70/30?

I used to inject the Novolin NPH, and it was cloudy and I needed to roll the vial. My wife used both "NPH" and "R" and the R was clear. Never have seen the 70/30 so don't know about that one from any experience.

And you only take it 1x/day at night? With my NPH I had to take it in 2 doses, 12 hrs apart for it to work correctly.

Thanks for your input. Hope I don't have to inject away from home/at work, a 2nd time per day. Mine must be the NPH. I left it on the bathroom sink overnight once, called the pharmacy, they said you can leave the open vial out all month. Just read the bottle, it said keep refrigerated. I'm sure the one night at room temp. didn't hurt it. Just started the Novolin on 6/4/12 & still take 2 Metformin w/breakfast & 1 with Lunch, total 1500 mg.

Once you open it Nph lasts 28 days (roughly 1 month). But then it gradually loses its potency after that time.

Of course you won't want to leave it in the car in the sun or allow it to freeze as that will ruin it quickly. Read the sheet that comes in the box with the vial in it to learn about the temperature requirements.

You need to refrigerate UNopened vials to prolong the useful life of the insulin.
